To make sure my data is properly protected, I keep a habit of lifting off monthly backups from my NAS to an external drive. I have couple of Samsung Story USB-drives dedicated for that purpose. This worked nicely for many years until I hit the brick wall. My combined monthly backup didn't fit the capacity of 1,5 TiB. It sure would be nice to have a "shingled" 8 TiB drive for that kind of storage, but unfortunately they are not available yet. See article New “Shingled” Hard Drives Hold Terabytes For Pennies A Gig.

In case you don't know what a Samsung Story drive is, it looks like this:

What I did was to pop the hood of my Story-drive to see what it had eaten. Very simple setup indeed, I went to a nearby store and got replacement 3 TiB WD Green drives (WD30EZRX).

Here is how the process goes. First pop the hood:

Quirk warning! The aluminium hood is held in place by 4 pieces of T9 Torx screws. The quirk here is, that T9 is not a common size. If you go to an average store, you'll find them having the smallest size of T10 (which is too big for this). Even my Apple repair kit doesn't have a T9, it has T8 and T10 pieces. I've taken apart Nokia phones, and they tend to have weird Torx-sizes, that's why I also have a kit which has T 4, 5, 6, 7, 8, 9 and 10. So, your biggest hurdle is to find a T9 somewhere.

When you have the aluminium cover removed, it'll look like this:

I included a blow-up of the warranty void -disclaimer sticker. I don't think Story drives have been manufactured for a while, so the warranty should be void anyway. Un-surprisingly, inside the box there is a Samsung 3,5" HD-drive, a HD154UI. Under the aluminium hood you will also find a plastic bracket. It just fills up the space making the actual drive fitting nicely and not moving. The bracket has a total of 8 plastic tabs holding it in place. I simply pushed one pair simultaneously from both sides, and I was able to lift the plastic holder up a bit. Then I just moved my fingers to the next pair and it moved more. The plastic thingie will look like this:

When the plastic bracket is gone, you can simply lift the drive upwards. It is held in place only by some rubber tabs, but the drive is essentially loose at this point:

Beware, that the S-ATA to USB -adapter (JMicron) is connected to the front-panel with a wire. That acts as a power on/off -switch for the entire thing. There are 4 wires in the connector, but I think only 2 of them are in use:

It is a pretty common connector and comes off easily by simply pulling it. The next thing is to remove the S-ATA / USB -converter -thingie from the drive. It is attached by a single #1 Phillips screw:

After the scew is gone, the entire converter-board will come loose from S-ATA -connector. Now that you have the hard drive almost completely stripped of all extra goodies, the last thing is to remove the rubber tabs and the kind-of-screws that hold them in place:

The rubber tabs or "pillows" come off by simply pulling them off from the sides. The metal "poles" are another story. They look like #1 Phillips, but the alloy they're made of is of poor quality. You can assume that a screwdriver isn't the primary tool here. I actually used pliers to turn them loose. Now everything is removed from the Samsung-drives, it's time to go big:

Just put the 4 metal screws back, fix the S-ATA / USB -converter board, attach the power-switch -cable, the rubber tabs and put the drive back to it's place. Like this:

After attaching the aluminium cover, it was a moment of truth. Does it still work? I plugged the power-cable and USB-cable back and went to my Linux:

Looked really good! Checking to see what my new drive had out-of-the-box:

It had nothing. Full of zeros. Not even a partition table. I'd launched the parted and went for GPT and a new Btrfs partition:
